我正在绘制有关房地产建筑商数据的图表。有几个建筑商以不同的价格出售不同类型的公寓。我想将数据绘制为公寓类型是 X 轴，公寓价格是 y 轴。无法保证每个建筑商都会建造相同类型的公寓，您可以查看下面的数据。当我在下面绘制数据时，它不是按 ApartmentType 排序的，因为不是所有的建筑商都提供各种类型的公寓。我正在寻找的预期输出是，即使 Builder 没有建造所有公寓，X 轴也应该是完整的。下面是样本数据。

plt.subplots(figsize=(20,8))
g = sns.lineplot(x='UnitSizeInBhk',y='AvgPriceInLakhs',data=top5buildersdatadf,hue='Builder') 
g.set_title('Top 5 Builders Data')
g.set(xlabel='Car Model Year',ylabel='Average MPG') 
plt.show()

仅供参考，这是原始图

当每个数据点总是只有一个时builder，apartment size您需要做的就是根据apartment size.

import numpy as np
import matplotlib.pyplot as plt

# Unsorted dummy data
n = 10
x1 = np.arange(n)
np.random.shuffle(x1)
y1 = np.random.random(n)

# Sort the x values from small to large
i = np.argsort(x1)
x2 = x1[i]
y2 = y1[i]

fig, ax = plt.subplots(1, 2)
ax[0].plot(x1, y1)
ax[1].plot(x2, y2)


#                Unsorted                                     Sorted

我会删除大小所在的数据点4+（在您的示例中，值与 for 相同5），因为这会阻止您使用数值。使用数值，排序是明确的，应该给出预期的结果：

# df = top5buildersdatadf
df.drop(df[df['UnitSizeInBhk'] == '4+'].index, axis=0, inplace=True)
df['UnitSizeInBhk'] = pd.to_numeric(df['UnitSizeInBhk'])

# do plotting
